Rihanna rakes in her 28th career leader on Billboard's Dance Club Songs chart (dated Jan. 21), as "Love on the Brain" bumps 2-1. Originally a ballad, "Love" was lifted into clubs via remixes from Barry Harris, Gigamesh and Don Diablo, among others.

In the tally of the most No. 1s in the chart's 40-plus year history, Rihanna remains second only to Madonna, who has scored a record 46 No. 1s. Late last year, Rihanna was named the No. 3 Dance Club Artist in Billboard's Greatest of All Time recap of the ranking's first 40 years.

"Love" is Rihanna's first No. 1 of 2017, following a year in which she earned four leaders, placing her in elite territory. Only four acts have scored four No. 1s in a calendar year, and Rihanna is the only one to do so four times (2007, 2010, 2011 and 2016). Lady Gaga tallied four in a January-December span twice (2009 and 2011) and Beyoncé (2009) and Katy Perry (2014) each earned the honor once.

Dating to the Dance Club Songs chart's Aug. 28, 1976 inception as a national survey, here's an updated look at the acts with the most No. 1s:

ENO ENTERS:Brian Eno debuts on Top Dance/Electronic Albums at No. 2 with Reflection. The 54-minute, single-track ambient electronic album sold 2,000 copies in the week ending Jan. 5, according to Nielsen Music. It's the seventh top 10 and ninth charted title for Eno, dating back to his first, The Equatorial Stars, credited to Fripp & Eno, in 2005. Last May, the producer sailed to No. 1 for the first time with The Ship.

Also new to the top 10 is masked DJ Marshmello, who rises 11-9 with "Ritual," featuring vocalist Wrabel. The track marks the second top 10 for each act; Marshmello marched to No. 4 in September with "Alone," while Wrabel hit No. 8 in June 2014 as featured on Afrojack's "Ten Feet Tall."
